    Trying to understand LXC RAM and SWAP allocation

    I have a workstation with 256 GB RAM, and by default the host has only 8 GB SWAP. With the two LXCs I have, as they can potentially use a lot of RAM, I committed 192 GB RAM and 64 GB SWAP to both. My question is, in a situation where both LXC reaches a high usage and they consume more than 256...

    Limit RAM used by ZFS?

    My 64GB RAM machine with ZFS seems to stabilise at 80% memory usage all the time for the root proxmox host. (Proxmox 6.2.4) I have several VMs running on top of it, all of them using no more than 20GB of RAM, so I suspect all the RAM usage is by ZFS on the root host. I've read several posts...

    pvestatd leak creates 3000+ processes, consumes all RAM & SWAP, and halts/reboots machine over a 4 hour cycle. Then repeats.

    This has occurred from the later PVE 6.1 updates (I think) and definitely all throughout PVE 6.2 (including 6.2-12) since about March 2020. Prior to this the system was rock-solid for about 1.5 years. Normal operation is ~10-12Gig usage (of 32G total). See attached picture for the cycle...
